BTK had a night race there a couple years ago and rented lights from a rent-all store that ran on diesal.
Fairly expensive I'd quess. Maybe someone local could check to see if this would even be an option

I would be in support of a little extra entry fee for a night race. Replacement of permanent lighting would be nice also!!! Perhaps our club could come to some sort of a long range plan with the owner to share expenses for track upgrades. (or something like that)_________________Mac
